I just did my alignment today. I had a piece of u-channel aluminum that I bungeed to each front wheel horizontally, centered vertically. Then I dropped a plumb bob from this instead of the tread: much easier! FWIW, it looks like 1 thread on the tie rod end is 1/4" of toe: wow!
I measured my camber with a level and tape. I figure I'm only within about +/-0.2* doing it in a hurry, but with a little work (another piece of u-channel and a verneer(sp?) caliper) I think I could be within 0.1 degree.
BTW, I'm running 3/8" total toe-out up front, -2.7 (or 2.5 or 2.9) camber up front, and all the caster that gives me. We'll see how the agressive setup works tomorrow...
